APEX is a new, enhanced version of the dCS Ring DAC™: the Digital to Analogue conversion system found inside all dCS DACs. First developed for our professional audio products, this unique system has been subject to continuous development and refinement over the past three decades, and remains renowned for its technical and sonic performance.
With APEX, we’ve reconfigured the Ring DAC’s™ circuit board and developed a new analogue output stage. This has allowed us to further reduce distortion, and increase linearity, resulting in a range of measured and sonic improvements – including an even greater sense of dynamic drive, detail, finesse and vitality.
VIVALDI APEX
The Pioneer
Engineered for the ultimate listening experience, the Vivaldi APEX reflects our uncompromising attitude, relentless innovation, and obsessive attention to detail. Featuring a dedicated DAC, Upsampler, Clock and CD/SACD Transport, it separates the core aspects of the playback process for a performance that is technically precise and musically profound
APEX DAC
The digital heart of the Vivaldi system, our world-famous DAC decodes audio with astonishing focus. Featuring the latest generation dCS Ring DAC™ APEX, it delivers a performance unmatched in its realism, depth, and emotion
Otherworldly Performance
With total precision and composure, the Vivaldi unravels even the most complex recordings with ease, projecting a sound that feels utterly natural and beautifully complete. Under its delicate hand and invisible touch, music comes alive, with each note unfolding to reveal a panoramic view of a recording or mix.
From the smallest inflections to the swiftest shifts in tempo and tone, it captures it all with a sense of perfect rhythm and flow. With its wide and far-reaching gaze, it uncovers not just the fine details in a recording, but the silences and spaces in between - the tension, drama and emotions that lie beneath.
Crafted for the purest musical expression, the Vivaldi is designed to disappear, leaving you absorbed in sound and immersed in the world that an artist creates. Its pioneering architecture builds on three decades of innovation to present our most ambitious system yet: a four-chassis design with almost limitless potential.
With the Vivaldi’s launch, we devised a blueprint for a new generation of digital playback systems. We reimagined our core technologies - including our Ring DAC™ system, clocking architecture and the dCS Digital Processing Platform - and developed a new technical DNA that has shaped the creation of each dCS product since.
Unrivalled in its sonic and technical abilities, the Vivaldi has earned global acclaim for its ground-breaking design and captivating sound. A product of visionary thinking, and fearless engineering, it remains the most revealing and lowest distortion playback system available - and its design continues to evolve.
With the Vivaldi APEX, we’ve once again redefined state-of-the-art in digital audio. We’ve further enhanced the Vivaldi DAC with the addition of our next generation Ring DAC APEX™ hardware. This major upgrade allows us to take the Vivaldi’s world-leading performance to a new level - resulting in an even more immersive musical experience.

Limitless Potential
Compatible with all high-resolution music formats, the Vivaldi is a system that can flex to serve whatever mood or music you ask it to. Whether you’re streaming or spinning discs, it offers superlative sound and an effortless listening experience. And with its wide range of settings and filters, its performance can be tailored to suit your music collection and audio setup.
The Vivaldi DAC features AES3, Dual AES, SDIF-2 and S/PDIF inputs, along with an asynchronous USB 2.0 interface. Its enhanced digital volume control allows direct connection to a power amplifier, removing the need for a separate preamp, and its maximum output can be set to one of four levels to suit a range of amplifier and speaker combinations.
Thanks to its high-performance UPnP streamer, the Vivaldi upsampler provides instant access to audio from a wide range of streaming services, including Roon, TIDAL, Spotify, Qobuz, Deezer and Internet Radio, as well as external devices and storage drives. Add a CD/SACD Transport and you have a system that delivers extraordinary sound from any digital source.
Playback is easily managed via our Mosaic platform, which allows you to browse music from multiple libraries and adjust the settings on your dCS system through a single mobile app. Available on all Android and iOS devices, it provides endless choice and complete control over your listening experience through a simple, intuitive interface.
APEX DAC Key Features
- dCS Ring DAC APEX™ hardware further reduces distortion and improves linearity for enhanced musical performance
- Utilises the latest generation dCS Digital Processing Platform for state-of-the-art measured performance and unrivalled fidelity
- Designed for maximum flexibility by accepting audio data from a variety of digital sources
- Flexible output configuration can be optimised in systems with or without preamplifiers
- Comprehensive clocking architecture plus an auto-clocking mode used in the Vivaldi range improves ease-of-use and minimises jitter
- USB interface allows easy connection to a computer, accepting PCM data at up to 24/384 and DoP (DSD/64 or DSD/128 over PCM)
- The interface runs in asynchronous USB mode, making the DAC immune to jitter from noisy computer master clocks
- Improved power supplies give lower running temperature and superior tolerance to AC supply variations
- Multi-stage regulation ensures sensitive analogue circuitry is unaffected by digital interference
- Separate power circuits for the digital and analogue sections further enhance the purity of the power supply
- Aerospace-grade machined aluminium chassis fitted with tuned acoustic damping panels reduces magnetic effects and vibration
- Features a full MQA™ decoder. This MQA™ implementation is unique, as it is the first opportunity to enable a DAC which, by providing exact rendering to beyond 16x (768 kHz), matches the desired temporal response with very low modulation noise
